The solder masks are generally used to reduce moisture infiltration to the PCB (thus can prevent leakage to some degree), but there may be surface-charge problems when using large area solder-masks. So the better approach is to use bare-copper guard areas around sensitive nodes. Using solder or...
What is Thermal Relay?
A relay that opens or closes contacts with a bending mechanism as a result of the difference in the expansion coefficients of a bimetal, which is heated by the current. ... The thermal relay is combined with a magnetic contactor because it cannot switch the main circuit...

Even if they last longer than you expect, they're not going to deliver the same performance after 10 years, even with routine maintenance. Typically, electric garage door openers have a lifespan of 10 to 15 years.or traditional or and traditional locks have a longer life than Electronic Garage...
To clean a corroded or oxidized PCB, Use cotton swabs and a cleaning solution such as isopropyl alcohol, baking soda and water, or even vinegar to clean it. Gently apply the solution to the affected area and wipe back and forth until the corrosion is removed. If necessary, leave some of the...
